THROTTLE CONTROL.

Application filed January 2, 1923. Serial No. 610,216.

To all whom it may concern.'

Be it known that I, WALTER J. SPrRo, a citizen of the United States, residing at White Plains, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Throttle Controls, of which the following is a specification.

This invention relates to a throttle con'- li trol and particularly to a construction adapted for application as an attachment to the brake lever and accelerator connection :tor an ordinary automobileconstruction.

The invention has for an object to prof vide a novel and improved construction of control lever pivoted upon a foot board to swing toward and from the same and having a control arm engaging an accelerator connection on saidboard and a rearwardly ex tending operating arm.

Another object of the invention is to present a new arrangement of control lever inl actuating levers are adjustably mountedfor positioning relative ltothe brake pedal and..

accelerator connection otan automobile. t Otherv and further objects and advantages of the invention will be hereinafter set t'orth` and the novel features thereofdeined by the appended claims.

tion embodying substantially a horizontal floor board 10 and an inclinedfoot board 11 through which the brake pedal lever 12 eX- tends and also the accelerator lconnection '13 which terminates in a push head 14.Y The control lever comprises a body portion 15 pivotally mounted in any desired manner, for instance by a yoke 16 carrying a pivot 17 journalled in the lugs 18 or the bracket 19 which is secured to the inclined toot board substantially in alinement with the pedal lever 12. The body 15 carries at its outer end an angle bracket 20 secured thereto by a clamping bolt Qliwhich also passes through and adjustably retains'in position a control arm 22 terminating at its free end in a plate 23 disposed in contact with the accelerator head 14. This plate maybe formed-with a roughen'ed tace Qtor direct application of the footfthereto in actuating the acceleratorl The angle bracket 2O also has adjustably clamped' thereto a rearwardly extending operating arm 25, which normallyV lies in a plane diagonal to that of the lever pivot, and may be of any preferred construction. The form herein shown comprises a channel iron 26 having longitudinal strengthening corrugations 27 and embracing a filler 28 vfor Contact with the heelporticn of the operacontainsa spacer vblock 29 kand is adjustably through the angle bracket and parts to be secured thereto.

Y ,9o The mounting of the Vcontrol arm permits arm in a vertical plane may be effected at both arms in order` to accommodate 4the, foot o ot' the operator and effect the most accurate and eliieient operation of the accelerator by a side movement of the operators heel while the `foot is supported upon the brake pedal. The control lever is normally supported in the full line position of Figure 2 by the spring tension of the accelerator connection and pressure upon the free end of the operating arm causes a downward swing of the outer end of the control lever carrying with it the actuating arm which depresses the accelerator button, as indicated by dotted lines in Figure 2. lVhen the operators toot is in the dotted line position ot' Figure 3 the accelerator is at rest and'when the heel is moved to the broken line, position in that figure the laccelerator is fully actuated and the parts are in the'dotted position' of Figure 2. Y

This invention is particularly designed as an attachment for brake and accelerator constructions now in common use and permits the operators toot to'be in constant contact with the brake pedal and in operative position for the accelerator. This avoids shitting the position of the foot and the accidental operation of either control member, while the toot is supported against the effect of road vibrations upon the acceleration. The structure'also provides means by which the brake and accelerator may be jointly operated to secure the most etlicient results in starting on a grade or against resistance. The mounting of the control lever is such that the accelerator restoring spring` is relieved of-its weight and is amply sufficient to return the lever to normal position when Ithe toot pressure is withdrawn therefrom. The lever when adjusted to proper position constitutes a unit member as both arms vare rigid relativelyftolthe pivot' and the lever body swings toward and from the inclined toot board while the operating` arm traverses a lateral and downward path toward the horizontal floor board.

lVhile the details of construction have been vspecifically shown and described, the invention' is not conlined thereto, as changes and alterations may be made therein without departing from the spirit ot the invention asdened by the following claims.

lVhat l claim is:

1. A pivoted throttle control lever, an operating member ext-ending rearwardly from the :tree end thereorn toward the axis oi' the lever pivot, and an oppositely extended control member upon the lever disposed to contact with an accelerator'.

2. A pivoted throttle lever` an operating member extending rearwardly from the lever at one side of its" pivot and diagonal thereto and an oppositely extended control member disposed to contacty with an accelerator.v

3. A throttle control lever comprising a body pivoted at one edge, a control arm extended laterally from the body in a plane substantially parallel with said pivot, and an operating arm extending in an opposite direction from the body and in a plane diagonal to the control arm.

t. A throttle lever comprising a pivoteol body, ran operating arm extended laterally therefrom at one side ot its axis, and an oppositely disposed control arm extended from the body at an angle greater than a right angle from the operating arm.

5. A throttle lever comprising a pivoted body, a control arm adjustably mounted thereon, a supporting bracket upon said body, and a rearwardly extending operating arm mounted upon said bracket t'or verticalV adjustment relative to said'control arm.

6'. Athrottle lever comprising a pivoted body, a control armv adjustably mountedA thereon, an angle bracket adjustably secured to said body, and an operating arm pivotally adjustable at its inner end upon said bracket.

7. A throttle lever comprising a body having a pivoting` yoke, an angle bracket pivotally adjustable upon said body, a control arm pivotally adjustable upon said body, a clamping bolt extendingthrough said arm, body and bracket, and an operating arm carried by said bracket.

8. A throttle lever comprising a body having a pivoting yoke, a pivot carrying bracket for 4saidyoke, an angle bracket secured to said body, a control arm thereon, clamping means for adjustably securing said bracket and arm, and a rearwardly extending operating arm pivotally adjustable at its inner end upon said bracket.

9. A throttle lever comprising a pivoted body, an accelerator actuating arm carried thereby, and foot operated arm extended rearwardly from the body and formed as a channel member embracing a projecting filler block to engage the heel of the operator.

lO. A pivoted throttle lever comprising a forwardly extending accelerator actuating member and a rearwardly extending foot operated member, said members being movaj'ble toward and from a foot! board in different paths of travel at one side of the pivotal axis of the lever.

11. The combination with a brake pedal and accelerator actuating member, of a control lever pivoted in substantial alinement with said pedal and having an operating arm at one side of the lever axis disposed tor actuation by a lateral movement ot the heel of a foot upon the pedal and a control lever movable toward and from said member.

12. The combination with a brake pedal and accelerator actuating member disposed upon an inclined foot board, ot a lever having a pivot parallel with said board, a horizontal arm 'from said lever movable laterally and downwardly toward the car floor, and an angularly disposed control arm movable toward and from the floor board.

13. The combination with a brake pedal and accelerator actuating member disposed upon an inclined foot board, of a lever having its pivot parallel with said board and in alinement with said pedal, a control arm upon said lever having a head in Contact With said member, and an operating arm extend-V ing rearwardly from the lever in a plane di- 10 agonal to the pivot thereof.
